  • Safety packaging for ampoules
    Patent number: 4155454
    Abstract: A safety package for an ampoule comprising a backing card, a cover sheet and an ampoule. The ampoule and the cover sheet are adapted to rupture upon the application of pressure to the backing card. The fractured segments of the ampoule are retained on the backing card, thereby minimizing the risk of glass splintering and cut fingers. After folding, the backing card provides a firm support which prevents ampoule spilling, and facilitates the filling of a syringe.
